SUPER BEAVER Drops Music Video for Gintama: Yoshiwara in Flames Theme Song "Sanzen"

Rock band SUPER BEAVER has officially released the music video for their new track, "Sanzen," which serves as the theme song for the compilation film Gintama: Yoshiwara in Flames. The video is now streaming online, coinciding with the film's theatrical run that began on February 13.

The track, whose title roughly translates to "Sparkling," is a high-energy rock song matching the intensity of the fan-favorite Yoshiwara arc. Ryota Yanagisawa handled both the music and lyrics for the song.

This compilation film is a key part of the massive 20th-anniversary push for the Gintama franchise, marking two decades since the manga's 2003 debut. Yoshiwara in Flames pulls episodes 139-146 from the original anime run, but reports confirm it includes new animated sequences and character appearances not present in the initial broadcast arc.

Fans first heard a preview of "Sanzen" back in December during Jump Festa '26, where the main visual and trailer for the film were revealed. The franchise has a history of these anniversary theatrical pushes, including the 4DX screenings for The Final films.

Naoya Ando directed the project, working from a script written by Taku Kishimoto. Character design and chief animation oversight was handled by Shinji Takeuchi at BN Pictures.
